Formula: Capacitor
Energy in the E-Field of a Charged Plate Capacitor

Electrical energy

Energy stored in the electric field of a plate capacitor. The formula is also valid for other charged bodies.


Capacitance is a measure of how good the plate capacitor is at storing charge on the plates.

Electric charge

The amount of charge that is on the capacitor plates (electrodes). On one electrode the charge is negative \(-Q\) and on the other electrode it is positive \(+Q\).
